Dear EarthTalk: I’ve heard that gas stoves are bad for indoor air quality, but what about gas furnaces and other gas-powered appliances typically found in homes?

—L.J., Ronkonkoma, NY

Natural gas is almost as ubiquitous an energy source in American households as electricity. Indeed, 48 percent of U.S. homes stay warm with gas-powered furnaces while 38 percent do their cooking with gas. But recent revelations about the negative effect cooking with gas can have on indoor air pollution has given rise to new concerns about other types of gas-powered appliances inside our homes as well.

Sure, your gas stove pollutes your indoor environment, but what about your other gas-powered appliances?
